WISN 12 News reporter Terry Sater sat down with the lead inspector Monday night to try and get some answers.

"Suffice it to say, we want to make sure everything we're doing is consistent with protecting Kathryn," Waukesha County Sheriff's Department Inspector Eric Severson said.

In an exclusive interview with WISN 12 News, Severson made it clear they don't have all the answers to the disappearance and reappearance of 15-year-old Kathryn Stalbaum.

"We are continuing our investigation. There's still quite a few questions that remain regarding what the activities were of Kathryn between Tuesday and Friday," Severson said.

The public was asked to help through the news media to be looking for the Genesee teen, and when she turned up in Chicago on Friday night asking for help from a police officer, many asked was she abducted or did she run away.

"Because Kathryn's a juvenile, because we're dealing with a minor, there may be questions you have, or that your viewers have, that we may never be able to answer publicly," Severson said.

"Was it still the right thing to ask for the public's help in trying to find a 15-year-old who was gone?" Sater asked.

"I think it is. In this particular case, from the beginning, we did not have a clear reason why Kathryn was missing," Severson said.

But now, but doesn't appear there was an abduction.

"The Sheriff's Department is not at this time looking at any person or persons of interest in this particular case," Severson said.

Sater talked with Stalbaum's family face-to-face Monday night, and while they didn't want to say if she went to school Monday, they said she's OK, and they are trying to move forward.
